Swarm cases

receipt 8256: KCNN3 in dopamine neurons, braak

power
full sample -0.39 (p 0.107, n 18), 95% CI -0.73 to +0.09. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.40 (p 0.099, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.69 (p 0.0014, n 18). not the mix.
skeptic
leave-one-out range -0.52 to -0.31, sign flips 0; without severely affected donors -0.39 (p 0.107, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.61 (p 0.0069, n 18) vs -0.39 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for KCNN3 in dopamine neurons.

follow-up registered; not confirmed in substantia nigra, an independent cohort.

composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: -0.20 (p 0.418, n 18). could be the mix.
skeptic
leave-one-out range -0.34 to -0.10, sign flips 0; without severely affected donors -0.19 (p 0.439, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.61 (p 0.0069, n 18) vs -0.19 in astrocytes. proposing oligodendrocytes.
